SEAT.

Specification of Letters Patent.

Patented Dec. 22), 1221..

Application filed October 27, 1920. Serial No. 419,878.

To all whom it may concern Be it known that I, DOUGLAS C. Gorr, a citizen of the United States, and a resident of Lynchburg, in the county of Campbell and State of Virginia, have invented certain new and useful Improvements in Seats, of which the following is a specification.

My invention is an improvement in seats, especially of the class designed for use with motor vehicles wherein the seat and the back are so connected that the seat does not move vertically relative to the back, during shock and jar, but wherein the parts are so connected and cushioned that resiliency will be provided, with the seat and back moving vertically together.

In the drawings:

Figure l is a front view of the improved seat,

Fig. 2 is a vertical section,

Fig. 3 is a section on the line 3-43 of Fig. 2,

iig. 1 is a top plan view of the base with the seat removed.

In the present embodiment of the invention, the improved seat comprises a base or riser in the form of a casing consisting of a body portion 1 and a base portion 2, the said portions being square in cross section, and the base being of greater area in cross section than the body. Both body and base portion are open frames, the base portion however being channel shaped, and arranged with its channel inward.

As shown in Fig. 2, the body portion 1 is provided at its lower end with an outwardly extending flange 3 which seats upon the upper side wall of the channel of the base. The seat proper is composed of sheet metal, and consists of a seat portion 4, a back portion 5, and arm portions 6 connecting the seat and back portions.

The seat portion 4 has a depending flange 7 at its edge, and this flange fits loosely about the upper end of the body 1 of the base. The back is upholstered as shown at 8, and an upholstered cushion indicated at 9 is arranged on the seat portion. This cushion consists of of a sheet of metal, having the upholstery on the upper face thereof, and such upholstery is merely a thin layer and is not resilient to any great degree.

The seat is supported by two substantially ittshaped members 10. Each of these merebers has at the free ends of its arms laterally extending lugs 11 which fit against the under face of the seat portion 4, and are secured thereto in any suitable or desired manner. The bodies of the ll-shaped members cross, and the said bodies at their 'crossing are clamped to flexible metal members 12, by means of a U-shaped clip 13 and a clamp plate 14.. The body of the clip is below the member 12, and below the bodies of the U- shaped members 10.

The arms of the clip 13 pass upwardly on opposite sides of the said flexible members 12 and U-shaped members end and through the clamping plate 1 1, where they areengaged by nuts to clamp the parts together. The members 12 cross each other at the clip, and the ends of the said members pass out at openings in the base, as clearly shown in Fig. 4. Coil springs 15 encircle the members 12 outside the base, between the base wall and nuts 16 threaded onto the said members.

The members 12 and springs 15 furnish the resiliency for the seat. When the seat moves downward, as indicated in dotted lines in Fig. 2, the springs 15 are compressed. The members 12 may bend down intermediate their ends as indicated in dotted lines in Fig. 2, and the seat may have sufficient yertical movement to provide ample cushionmg.

In order to limit lateral movement of the seat with respect to the base, a radius plate 17 is hinged at one end tothe under face of the seat portion 1- of the seat. and the other end to the front wall of the base near the top thereof. This radius plate limits the lateral movement of the plate forwardly and rearwardly, and also laterally.

Referring to Fig. 2, it will be seen that the upholstery of the back has a cavity at its upper end, between the same and the back portion 5, within which is arranged a. series of coil springs 18..

Referring to Fig. 2, it will be seen that there is ample unobstructed space within the U-shaped members for receiving a tank indicated at 20. This is a feature of importance, since the seat is more especially designed for motor trucks, and in these trucks the gasolene tank is arranged beneath the seat. The tank is so spaced that the U-shaped members may move freely vertically without in terferenoe from the tank.

The radius plate has an opening 21 through which access may be had to the fill ing plug of the tank. The arrangement of the back with the coil springs at the top, and with the lower part of the back firmly cushioned, provides ample cushioning effect for the shoulders of the rider, and without the uncomfortable rubbing that is incident to this character of seat.

Referring to the drawing, it will be seen that the lower part of the seat back is not provided with a spring cushion, and this portion of the back provides a relatively firm back support where it is needed. Then the occupant is pressing forward with his feet, as when applying brakes to hold the clutch disengaged for long periods, he should have a suficiently firm back support to prevent slipping backward in the seat. The seat'bottom is formed with a central ridge'extending from the front of the back along the center line, the purpose of this ridge being to make the seat conform to the shape of: the user more nearly,- thus making the scat more comfortable.

I claim:

1. The combination with a body, oi a seat thereon, U-shaped supporting members having upwardly directed arms connected at their ends to said seat, and means yieldably supporting said U-shaped members for vertical yielding movement.

2. The combination with a seat, of. crossed supporting devices having upwardly directed arms connected to said seat, and means connected to the crossed portions of said seat supporting devices for supporting the same for vertical yielding movement.

3. The combination with a body, of a seat thereon, U-shaped seat supporting devices having upwardly extending arms connected to said seat, means yieldably supporting said U-shaped supporting devices, and a radius member connected to said body and said seat. I i

i. The combination with a body, of a seat thereon, seat supporting devices having up wardly extending arms connected at their ends to said seat, and a plurality of flexible elements connected to said body and said seat supporting devices.

5. The combination with a seat, of crossed seat supporting devices connected to said seat and radially arranged rods connected to the crossed portions of said seat supporting devices.

6. The combination with a'seat, of U- shaped supporting devices connected to the seat and having their bight portions crossed, and means connecting the crossed bight portions of said U-shaped supporting device.

7. The. combination with a seat, of U shaped supporting devices connected tothe seat and having their bightportions crossed, fastening devices joining the crossed bight portions of said U-shaped supporting devices, and yieldable members supporting the U-shaped devices and connected to said fastening devices.

8. The combination with a seat, of supporting devices for the seat, a plurality of radially arranged flexible elements connected to said seat supporting devices, and springs connected to said flexible elements and yieldably limiting the movement of the same and said seat supporting devices.

9. The combination with a body, of a seat thereon, seat supporting devices within said body, flexible elements connected to said seat supporting devices and passing through saidbody, 'and'springs confined between the ends of said flexible element and the adja cent portions-of said body.

lOfThe combination with a body, of a seat thereon, U-shaped seat supporting devices connected to said seat and having their bight portions crossed, flexible elements connected to the bight portions of said U- shaped supporting devices and passing through said body and coiled springs confined between the ends of said flexible elements and the adjacent portions oi said body.

11. The combinationjwith a seat, of supporting meansthere'for, and radial horizontally arranged yieldable supporting devices for said supporting means.
